HARVESTER.

SPECIFICATION forming part of Letters Patent No. 272,217, dated February13, 1883.

Application filed October 1G, 1882. (No model.)

To alt trimm it 'may concern:

Be it known that I, JOHN S. DAVIS, of Toledo, in the county ofLucas andState ot Ohio, have invented certain new and useful Improvements inHarvesters, of which the following is a specification.

My objects mainly are to provide a strong, light, and durable machine,and to enable the driver readily to control its operation.

As shown by the accompanying drawings, my invention is applied to amower or grasscutting harvester. -Some of my improvements mayadvantageously be used without the others, and in connection with eithergrass or grain harvesters.

Figure l is a plan or top view with parts broken away. Fig. 2 is a sideelevation with .parts broken away, other partsin section, and some partsdetached. Fig. 3 is a front elevazo tion, with the tongue in section.Fig. 4 is a View, partly in side elevation and partly in scction on orabout the line 4 4 of Fig. 1. Fig. 5 is aside elevation, showing detailsof thedevices for throwing the cutter-actuating gearing into and out ofaction. Fig. 6 isa plan View of the box or bearing-sleeve for connectingthe pitman and wrist-pin ofthe crank-wheel. Fig.

7 is a view in section on the line 7 7 of Figs. l-

and 6, showing' details of the connection between the pitman andwrist-pin boX. Figs. S

and 9 are respectively a side elevation and a plan view ot' the shoedetached. Figs. l() and 11 are respectively a side elevation and a planview ot an eccentric by the oscillation ot' which the shoe is rocked.Fig. 12-is a plan view ot' the adjustable bracket and its turningeyebolt for connecting the drag-bar and main-frame arm.

A two-part main frame, A B, of substantially 4o rectangular form, isprovided at its front inner corner with an inwardly-projecting arm orside extension, A. This arm crosses in advance of and extends inside ofthe inner one of a pair of driving-wheels, B B2, which arelooselymounted on their axle A2. The art A of the mainframe and the armA', as shown,

are formed of one piecel ot' wrought-iron, consisting of a bar bent intoshape and riveted at a, one end of the bar extending slightly for- 5oward frotn'the innervfront corner ofthe frame proper, and being bent rstdownward and then inward to form the side arm, A', crossing beneath thetongue B3. The tongue extends back by the side ofthe frame, and isstrongly securedto the inner side thereof by bolts ain this instancethree in'number. Another bolt, c2, connects thetongue and arm A of the`frame. Strength and stiffness are in this way attained. The portion Bofthe main frame is forked, is of cast-iron, and constitutes abedpiecewhich supports the gearing, and is provided with the boxesfor the axleand gear-shaft ing. This bedpieee is fitted to the bent tra mebar A andmainly within it. Bolts b b b b2 b2,

i Figs. 1 and 3. passing through suitable iianges of the bed-piece,serve to firmly unite it with the frame-bar. Byvtorking the bed-piece,as shown, desired strength without unnecessary weight is secured. Theaxle turns freely in -sectional boxes a3 a3, and the driving-wheels areconnected with the axle by backing-ratchets, or so as to cause it toturn therewith when the machine is advancing and leave it free w henbacking. The ratchets U O are fastened tothe axle, and spring-pawls c,for engagement therewith, are pivoted to spokes ofthe drivingwheels. Theratchet O for the outer drivingwheel, and an internally-tootheddriving-gear, 1 A

D, are rigidly connected, either by casting them together or making themseparately and firmly uniting them. They are best made'in one castingand connected by spokes, as shown.

A pinion, D', is loosely mounted on a shaft, E, supported in sectionalboxes c c by the bedpiece B. The pinion is driven by the gear D, andengaged with and disengaged from its shaft by suitable clutch mechanismto throw the cutters into and out of gear. As shown, the shaft E has atixedly-attached cross-pin, d, at its outer end, with which the pinionis adapted to be engaged, to clutch it to its shaft, by cross-grooves-inthe pinion-tace, into which the pinion takes, as is well understood,when the pinion is slid toward the end of the shaft and against the pin.The pinion isislid into and out of engagement with the shaft-pin byclutch-shipping mechanism, shown as formed by a forkended lever orrocking shipper, F, engaging acollar on thepinion-hnb and mounted on asupporting arm or bracket, F,secured IOC to the bed-piece bythe boltswhich secure the upper section ofthe box e in place. A pivotbolt orheaded pin, j', for the shipper` is provided with a spring,f', actingwith a tendency to hold a stop-lugj'z, on the shipper against movementoutward or away from the upperend of the bracket F". The stop f2 holdsthe shipper against accidental movement, and so te tains the pinion outof or in clutch with its shaft, according to the position ot' theshipper and whether the stop is bearing against the outside of thebracket, as shown, or against the opposite side thereof.

A bevel-pinion, G, on the crank-shaft G' is driven b v abevel-gear,l1,on the shaft E. The crank-shalt is tnonnted in sectional boxes gg'.rlhe box g' anti the other boxes of' themachine are so constructed andpacked as to admit ot' adjustment to take up wear. The box g' isvertically divided, aml is provided with two sets of bolt-lugs orsecuring-ears, g2 g2, for an obvious` purpose. The packing material(leather, sheetmetal, Stc.) G2 is secured between the box-sections tothe thickness needed.

A drivets seat, H, is so mounted as to be located directly over the axleAz. thus rendering variations in the weights ot' drivers or the presenceot' a driver in his seat immaterial in balancing the machine oradjusting the weight on the neck-yoke. The seat-spring is shown asdouble, consisting otthe stem or main part H' and the leat'H2. Abracket, It, secured to the trout ot' the main frame by side lugs andbolts, h'h', connecting it with the frame-bar A, serves to connect theseat-spring with the frame. A bolt, h2, unites the spring and bracket.Thedownwardly-extendedforwardly-bent end of the spring supports atoolbox and footrest, I. The spring-securing bracket has side tianges,'i i', to provide a seat or socket for the better attachment oftheseat-spring. A stoplug or hook-like proiection, t', on the bracket isshown as formed with the llange i'. rlhis stop serves to engage a lever,l', as farther on explained.

The side arm, A', ofthe main frame is braced against downward strains byan inclined bar or bracing-strap, J, secured at one end to the tongue bythe bolt a2, and boltedor riveted at its oppositeend to the frame-arm.An inclined brace, J', extends forward from tlte frame-arm to thetongue. This brace-rod is adjus'ably connected to the under side ot' thetongue by means of a bracket, J2, secured in place by a side tlange,j,anda bolt, 7", and its nut. The forward end of the brace-rod isthreaded, passes through a perforation in a rib on the under side ot thebracket, and is held by nuts on each side ot' the rib. (See Figs. 1 and3.)

The rear end ot' thel rod is connected with the frame-arm, near itsouter end, by a bolt,j2.

A vet-ticaily-vibrating and axially rocking drag-bar, K, hasjointedconnection at one end with the trame-extension or side atm. A', andextends back outside of and parallel, or nearly so, with the face ot"the inner driving-wheel.

To provide for the rocking of the drag-bar about its longitudinal axis,adapt it to vibrate vertically, and provide for readily tilting theparts together, the connection between the drag-bar and traute is iliadeas follows: A bracket, K', is formed with an edge tiange. It', to bearagainst the front edge ot' the framearm, with a slot, k', by which it isadjustably held to the frame-arm by the boltf', an l with a socket orbearing, k2, for a turning eyebolt or swivel-link, liz, secured to thedrag-bar by being passed through an eye therein. The bracket is securedto the under side ofthe frame-arm. In this way, as will be obvious, thedrag-bar may be vibrated about the framearm by raising and lowering itsrear end, and it is rocked axially by means ot' the lever I', whichcrosses above the drag-bar, and is pivoa-.tlly connected to it by meansof the upwardly-projecting lugs l l ot' a bracket, L, bolted to theunderside ofthe drag-bar. These lugs extend up at thtl outer edge ot thedragbar, ami a pitt or bolt serves to connect; the lever with them. Therocking lever extends toward the foot-rest, in front ot' the innerdrivingwheel and beneath the tongue, and is bent upward and thenhorizontally, or nearly so, terminating near the outer driving-wheel ina. foot-rest or curve, L', convenient to the foot of the driver while inhis seat. The tongue serves to prevent too great upward movement of thislever when the drag-bar rocks in one direction, while the stop t" servesto hold the lever at the limit of its downward movement when thedrag-bar is rocked in the opposite direction, for [urposes farther on tobe explained. At its rear end the drag-barK passes beneath a `shoe, M,and is then bent upwardly and jointed to the heel of the shoe. A bearingsleeve or socket, M', at the npturned rear end ot' the drag-bar, lugs mm on the shoe-heel,

and a pivot-pinna', serve to make thejointt-d connection between theshoe and trat-bar. The shoe is made to vibrate vertically byrocking itabout its heel-pivot; by the means and in the manner next to bedescribed.

Atitst'orward end theshoeprtectsupwardly, and terminates in a bearingring or socket, N, l'or an eccentric, shown as formed by a disk, N2, anda piti, n, rigidly but detachably connected with it nearits periphery,and constituting tite shaft about which it is rocked in the shoebearing.A hollow eccentric stand and bracket-housiug, N',is tirmly connected byits tianged base ami bolts to the drag-bar. A rear opening, fn', in thehousing serves to admit the front etnl ot the shoe, with theeccentric-disk in place, (bet'ore hinging the shoe-heel to the drag-barand without the pin u,) and a front opening;

n2.in tlte housing accommodates a rod, O, which is pivotally connectedwith a short arm or ear, o, on the eccentric. At'ter the parts areadjusted tlte pitt n is driven tightly in place. Slots U' (only one ot'which is shown) are made opposite each other in the side walls ot' thehousing, for the eccentric-axis to playin as loq IIO

Ils

the eccentric is rocked by the manipulation of the rod O by means suchas soon to bey described. This rod is connected by its beltt rear endwith the eccentric-arm before the eccentric and shoe are inserted in thehousing. Disconnection of therod is preventedv by its contact with theadjacent wallet' the housing. A side lug or dog, o', on theeccentric-arm o comes in contact witha stop-lug or shoulder, 02, on theeccentric-bearing, to litnit the rock of the shoe upward at its front'bythe oscillation ofthe eccelltricin thedirection in which it isturued bypulling strain on the rod 0. rEhe downward movement of the front. endot' the shoe, as` the shoe is vibrated aboutits heelpivot by the thrustof the rod O, is limited by contact of the shoe withv the drag-bar.v

. A shoe-tilting lever, O', connected with the rod O, is pivoted uponastaud or bracket, O, which is secured to the frame-arm A by its flangedbase and the boltjz, which secures the drag-bar bracket K and brace-rodJ to the frame-arm. rlhe tilting lever is provided with suitable detentdevices, shown as consisting otl the rack-teeth l?,v formed with thebracket O2,and the controllingrod P", connected with the spring-actuatedrocking stop-lug or donr p, pivoted to the lever to engage the rack. Thelever O is adj ustably connected with the rod 0 in sttch manner as otadmit of the turning of this rod to accommodate the axial rockingmovement. of the drag-bar K. A socketed screw-threaded coupling-sleeve,p', h'tted to the piti or bent end p2 of the lever by its socket and thethreaded endof'the-rod O, ,is screwed into the sleeve.

An inclined rod, Q, connected at its oppothe drag-bar, and a perforatedlug, q, on the housing receives the threaded rear end of the brace-rod,which is secured byjam-nuts ou op-.. A linger-beam, Q', is.

postte sides of the lug. rigidly secured at its heel end to theshoe-'insuitable way, and is provided with the usual guards and cutters ,tocompleteA well-known' cutting apparatus.

A hinged brace-bar or coupling-arm, R, cou-` nects the cutting apparatuswithv the outer rear corner ofthe main trame', as will fartherv on 4befully explained.

Frotn the above description it will be seenV that while the outer end ofthe cutting appa-v ratus is prevented from dropping too low by contactof the lever l with the under side `of the tongue, or by thepressure ofthe drivers,

foot, the usually employed device for stiftening thelnger-beatnpreparatorytto raising its` outer end is dispensed with, and the outer,

end of the cutting apparatus raised simplyfby depressing the treadle endof the lever l', and

so vrocking the drag-bar. It will further beseen. that in addition tothe facility ai'orded the driver lor tilting the guards by theemployment of theecceutric, &c., the cutting apparatus is very stronglybraced against back ward strains by means of the extended front. endofthe'sh'oe, the housing in which it works,

and a shoulder or-projection, q', on the shoeA which,fby contact withthe wall of the bons-- ing, lessens the strain upon the shoe front oreccentric-bearing arising` fromv backward or thrusting strains on thecutting apparatus.

The coupling-arm R is pin-jointed at itsheel end to lugs Trot' the mainframe. Theselugs are formed with lthe rearwardly-projectin g. portionofthe bed-piece ofthe fratrie near the outer rear corner ot' the bentframe-bar. The connection` between the outer end of the couplingarrn andthe cutting apparatus is by way ot' short arms. or lugsvR r on the frontportion ot' the shoe. The coupling-arm is pinjointed to thosev lugs, oneof which is made longer than the other, and provided witha recess orhalfround groove, s, initstop, (see Fig'. 9.) so that when the cuttingapparatus is elevated for transportation itv may beheld up by a piu orbolt passing through a hole, S, in the couplingarm andengagingthe-grooves ofthe arm R.-

The cutting apparatus is raisedand. lowered .bodilyorthroughoutitsentirelength by mea-ns 'of a rocking lifting-lever,T,ilexibl v connected with the coupling-arm. This lever ismou'nted at ornear thel inner rear corner of the main framethroughor by way of theheel end of the tongue. hook, t,.and segmeutsheave t, and is pivoted att2 to a frame-stand or bracket, T', which is secured by its flanged baseand the rearmo'st The lever is provided witha IOO oneof the bolts ct'tothe tongue-heelaud fraruebar. A chain, T2, connects the lever-hook andthecoupling-artn. t The lever, when rocked forward and downwardto thelimit of its movementin raising the cutting apparatus, engages`v with acatch-bar or detent formed by the hook or. catch u of a exible bar orstrap iron, U, se-

A side lugvor latcrankfwheel V bythe-ans of a threaded coupling-sleeve,V2, into which the threaded-end of' the pitman is screwed and held byalam-uut,

c2, and a box or bearing-sleeve, V3, ittingthe wrist-piu and pivoted toits coupling-sleeve. The boxV3 is provided .with an oil-hole,`and heldto the wrist-piti bya nut and washer, as usual, and has a perforatedear. 113, which titsA between corresponding ears, V4 V4, on thecoupling-sleeve. A tubular pivot-pin, 114, pref erably made of wood, toserve as au inexpensive and readily-removable bushingand pre-rv ventAnoise, passes through the holes in the ears ot the coupling-sleeveandbox, and is re- Iltnovablyheld to its place by a screwbolt, 115,'

with its nut and washers.

l do not herein `claim the above-described means for connecting thepitman and crankwheel.

The pitman is connected with the knife-heel or inner end of thecutter-bar by a ball-audsocketjoiut in the following way: The innersectionor heel attachment, W, of the knifebar has the hollow ball wformed with it, and the pitman is forked or split, and each of the twoarms W W of the fork is provided with a half socket or cup, w, whichembrace the ball and are caused to properly clasp it by means of theadjusting screw-bolt w2 and its nut. One. of the jaws or arms W of thepitman is threaded for engagement by the screw of the bolt, so that thearms may be separated or drawn together, as desired, and when adjustedbe held, with the aid of the jam-nut, on the bolt end. In this way wearmay be compensatedfor readily. Oil-holes are drilled in the oppositesides of the ball te, where itis embraced hy the cups w ui', and anopening is made through the top ofthe ball, so that it may be filledwith lubricant (oil and cotton waste, tallow, cbc.) to keepthejointlubricated without waste.
